in Lib.mesh.generate

Generates a mesh by extruding a set of points along a set of other points.

The extrusion is done along the z-axis. This means that the rail points should be aligned in a way that z is pointing along the rail.

Also, the normals are directly taken from the extruded points' z-axis. You can use the [VisualizePoints] to verify the alignment and adjust it in [TransformPoints] in point space.
